Transformer model enhances cooperative multi-AP OFDM uplink reception

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel cross-attention Transformer model designed for cooperative multi-access point (AP) OFDM uplink reception. This model efficiently fuses signals from multiple receivers, adapting to varying link reliability and channel conditions without requiring explicit channel estimates. Tested over realistic Wi-Fi channels, the Transformer demonstrates superior performance compared to traditional methods and existing neural baselines, achieving results comparable to perfect channel state information while maintaining computational efficiency on standard hardware.

    Scalable Cross-Attention Transformer for Cooperative Multi-AP OFDM Uplink Reception

    arXiv:2602.04728v3 Announce Type: replace-cross Abstract: We propose a cross-attention Transformer for joint decoding of uplink OFDM signals received by multiple coordinated access points. A shared per-receiver encoder learns the time-frequency structure of each grid, and a token…
